A Smooth Gliding Surface for Opposing Bones is Provided by ____

Question

​A smooth gliding surface for opposing bones is provided by ____.
A) ​desmosomes
B) ​synovial fluid
C) ​sebum
D) ​sweat

Accepted Answer

Synovial fluid helps to reduce friction and provide a smooth gliding surface for opposing bones in synovial joints. Desmosomes are protein structures that help to anchor cells together, but do not provide lubrication for joint movement. Sebum and sweat are both involved in skin function and do not directly relate to joint movement.
